With President Obama calling for robust investments in repairing America’s crumbling roads and bridges today, State PIRGs released data today documenting the number of “structurally deficient” bridges in seven states.

President Obama was right to call for bold new investments in our outdated transportation infrastructure. Fixing our roads and building new railways won’t just put thousands of unemployed construction workers back to work now; it will allow America to meet the demands of a competitive 21st century economy.

The politics of high-speed rail can be bizarre. Few people actually oppose connecting our cities with fast intercity trains. Most of the industrialized world has already shown that the idea is popular and works well. The politicians that do the most to prevent high-speed rail generally claim to be fans of bullet trains who just want the task to be left to the private sector.

Private sector companies are likely to play a major role in the construction of high-speed rail lines in the United States. Public-private partnerships – or “PPPs” – have come to play an important role in the construction of high-speed rail lines around the world. The experience with high-speed rail PPPs, however, has been mixed. While PPP arrangements have brought private capital and expertise to the task of building high-speed rail, PPPs have also resulted in cost overruns, government bailouts, and other serious problems for the public. America must learn from these experiences and pursue PPPs only in keeping with key principles designed to protect the public interest.

You'd think the only reason American infrastructure lacks funding was rules preventing private businesses from throwing money at it. Last week Congress introduced a couple of bills to solve this imaginary problem and one that would set some ground rules to protect the public.

Highway advocates often claim that roads “pay for themselves,” with gasoline taxes and other charges to motorists covering – or nearly covering – the full cost of highway construction and maintenance. They are wrong. To have a meaningful national debate over transportation policy – particularly at a time of tight public budgets – it is important to get past the myths and address the real, difficult choices America must make for the 21st century.

As America moves toward construction of new high-speed rail networks in regions throughout the country, we have much to learn from experiences abroad. High-speed rail lines have operated for more than 45 years in Japan and for three decades in Europe, providing a wealth of information about what the United States can expect from high-speed rail and how we can receive the greatest possible benefits from our investment.
